Prevent Large Title from Moving Down when Refreshing TableView

I have implemented the Large Title for UITableView correctly. The Navigation bar collapses when scrolling down the table view. However, when pulling to refresh, the Large Title moves down the screen instead of staying stationary. I suspect that this is the default behavior. Is there a way to keep the large title stationary when pulling downward to refresh the UITableView?
